Re: clutch slipping (richjeanne93vette)
Replace it immediately before you destroy the very expensive flywheel. Clutch longevity depends on the abuse it receives. 50,000 to 100,000 miles is a reasonable range for a clutch to last. There is no reason a stock clutch shouldn't be used for replacement.
I would advise that you take your vette to a specialty clutch house. The dual mass flywheel can be turned to true the surface, but not to the extent of a normal flywheel. Shop the area for prices.
(When shopping for a price, I would recommend against telling anyone your name is "Rich Jeanne")

Mine went at about 64,000 miles. Of course several of those were a 1/4 mile at a time.
I had a stock clutch put in, the flywheel lightly resurfaced and a new rear main seal replaced at the same time, $850.
Just so you won't get sticker shock.

Re: clutch slipping (richjeanne93vette)
I agree with oldman, fix the clutch immediately. If you push it, you will ruin the flywheel and that is $1000 in an of itself. That would make it about a $2,000 problem. If you fix it quickly you can probably reuse the flywheel unless it is cracked or was abused then you can do the clutch for $650-$1000 depending on who you know.
To answer your question, a clutch on a C4 definately takes some time to put in especially if you have never done a C4 before.
I have a 123,000 miles on my original clutch and am going to replace it with a stock clutch when it decides to go kaput. However, there are many aftermarket clutches you may want to consider if you want a more aggressive clutch.
I would find a shop that specializes in Vettes and pay them in cash.
You would hate to do all the labor and then put it all back together and have something go wrong. Then you would have to pay someone to do it anyway.

Re: clutch slipping (richjeanne93vette)
My dualmass FW had some burning, but we changed the clutch before the rivets hit. It took a few machine shops before one could cut it. Only took off 6 thousands and it worked out fine. Officially from GM it is a no no to cut them. I used a stock clutch.
I highly recommend a stock replacement if you do not plan on 400+ HP mods. If you go with an aftermarket performance type, get some good advice as there are a lot of little traps you will need to understand. If the flywheel is toast it may be cost effective to go with a single mass setup. But there are trade offs and potential risks. Do a search in tech. :yesnod:

Re: clutch slipping (Yello95)
How can I tell if I have a single or dual mass setup in my 1995 lt1 without taking out the ZF6? :confused: Thanks
Here is the engine side of a dual mass, you can pull the insp plate & should see this...
and here is the clutch side...

Re: clutch slipping (superlund)
It looks like the friction side of the fly wheel is sheet metal riveted to the fly wheel? No wonder you can't cut them. There isn't much to cut.

If it has not been replaced with a single mass by someone, then it's a dual mass, there never was a single mass/ZF Trans Combo from the factory...
